Process industrial loads are increasing due to expansion of existing manufacturing units. Increasing of loads will increase the power requirement which is reflected at the distribution level. Feeding the additional loads existing switchgear to be modified and for meeting load requirement additional source of distribution transformer to be added, which it may not be an economical solution. To meet the additional load requirement of industries, two transformers need to be operated in parallel in continuous mode. Bus fault current at LV switchgear is the main constrain with parallel operation of the distribution transformer. Due to increase in fault current, existing switchgears bus bar design capacities may not be adequate, generally in India fault current at LV side switchgear bus bars will be designed for 50kA withstanding capacity. Approach is to reduce the fault current below design fault current with parallel operation of transformers. This approach is mainly safeguard the switchgear equipment during parallel operation of transformers and also avoiding adding additional transformers in distribution network. This paper proposes the method of utilizing series FACTS device Interline Power Flow controller (IPFC), connected in LV side to control the power flow and reduce the fault current on switchgear bus bar during transformer parallel operation. The controller used as reference design fault current method and injected the required voltage in a distribution side during fault condition to achieve desired fault current. The distribution network consider for analysis is one of the Indian 800MW Thermal power plant Water system LV switchgear and analyzed short circuit current on switchgear bus bar with and without IPFC by using ETAP and MATLAB/SIMULINK model and compared the bus short circuit current for different ratings of transformers connected in parallel to LV switchgear.

The energy crisis is something that is vastly overlooked but will cause major issues in the near future for humankind. This paper outlines the methodology of designing and implementation of a solar powered system, which can be used to supply energy for high power appliances with the use of Supercapacitors. Using a supercapacitor bank to ensure the constant supply during shading, the system mainly relies on MOSFET's, controlled through an Arduino Nano. The microcontroller will switch between the four working phases depending on the voltages of the supercapacitor bank and PV array. The system will be running on either the PV supply, the PV supply while charging the Supercapacitor bank, the Supercapacitor bank alone, or failing which the main grid. The Supercapacitor bank is charged by the PV supply.

Power system stabilizer (PSS) has been used for decades for its high effectiveness to provide positive damping torque to synchronous generators through the excitation system. Its implementation aims to improve the stability of the synchronous generators in response to severe disturbance. However, with recent power grid expansion through integration of inertial-less renewable energy, the effectiveness of PSS in improving transient stability of inertia-reduced hybrid power system is concerned. Therefore, this study aims to verify the effectiveness of PSS in the hybrid diesel-wind-solar PV power system. Subsequent to this, the impact of PSS1A and PSS4B on the transient stability of the hybrid system are compared by simulating different faults events. From the results obtained, the implementations of both PSS1A and PSS4B can still maintain the steady-state stability of the hybrid power system with improvement made on transient stability, particularly in stabilizing rotor angle and post-fault power recovery. The comparison between the two PSSs shows that PSS4B outperformed PSS1A in damping the system oscillation.

The necessity for smart electrical systems having minimum power loss and environmental impact is providing impetus to go for Distributed Generations (DGs) which may offer several other advantages such as reduced transmission and distribution system resources, increased reliability, better power quality. Proper placement of DGs, such as wind turbines and photovoltaic units, in the distribution system is still a very challenging issue for obtaining their maximum potential benefits. Optimal location and sizing of distributed generation (DG) is a key for loss minimization and improvement of voltage profile in radial distribution systems. The present paper proposes a loss sensitivity factor for DG placement in distribution network for power loss minimization while maintaining the voltage profile in the system within the specified limits. An Analytical approach is proposed for sizing of renewable DGs such as solar, wind and Hydel Units for minimizing active power loss, annual operation costs (installation, maintenance, and active power loss costs). This is tested in different cases. All cases are compared to identify the superiority of the proposed method. The proposed method is tested on IEEE 33 Bus Radial Distributed System to demonstrate the performance and effectiveness in ETAP software.

Lightning and power surges are phenomena where the over spike occurs for a short period of time. There are few main sources of power surge which are switching, lightning strikes, coupling, electrostatic discharge and nuclear electromagnetic pulses. To minimize the damage due to surge activities, proper installation of grounding system is essential to suppress the surge into the ground. However, there are some systems where physical grounding is not possible such as vehicles, ships and aircraft. In the absence of a proper lightning protection system, direct lightning strikes can cause lethal accidents in vehicles, particularly in aircraft and ships. In the current research, the impact of surge and its protection method for float ground systems were investigated. Various test waveforms as specified in different standards are simulated and examined. These surges can be modeled according to the IEC standard 1.2/50μs opened-circuit voltage and 8/20μs shorted-circuit current waveform.

Position sensors in permanent magnet synchronous motor (PMSM) are restrained in some applications because of the space restriction and the reliability of the system. A marginalized particle filter (MPF) can used to staminate the speed of the motor by combining a Kalman filter (KF) with a particle filter (PF). In the MPF algorithm, the rotor position of the permanent magnet synchronous motor (PMSM) is represented by a set of particles, and the rotor speed associated with each particle is estimated by using the KF. The PF here is used to handle the non-Gaussianity and nonlinearity of the system. In this paper, the uniform distribution of particles is proposed to replace the traditional Gaussian distribution of particles in the PF to get better performance at the low-speed range. The motor drive system prototype is built using a TMS320F28335 digital signal processor as a controller core. The proposed improved PF is used in the sensorless speed vector control PMSM system. The experimental results show that the proposed PF with a uniform distribution of initial particles enables more accurate speed estimation in the low-speed range compared to the conventional Gaussian distribution, while increasing number of particles also helps to improve the accuracy.

There is a spasticity in symptom that stroke hemiplegia patients usually develop. In addition to stroke, the spasticity is developed by head injury and spinal cord injury. The spasticity occurs mainly in limbs such as fingers, elbows, and ankles. Then patients cannot move their limbs as the symptom. Activity of Daily Living (ADL) is influenced by the symptom in their daily life. Therefore, it is important to evaluate the spasticity. Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) are mainly used as the evaluation method of the spasticity. However, each evaluation method is a manual test by an examiner. Therefore, the evaluation is not reliable because the experience, intuition, and subjectivity of the examiner influence the evaluation. In this study, we develop a measurement system for spasticity. First, we use the motor to flex the right arm of subjects. Next, we measure reaction forces and angles in flexion. Experiments perform in the normal state and the spastic state. In the normal state, subjects apply no force. In the spastic state, subjects apply the force at around 45 degrees. The flexion speeds are 1 rpm, 2 rpm, 3 rpm and 4 rpm. We perform the measurement between 0 degrees to 90 degrees in all the experiments. In this experiment, three healthy adult men participated. First, we performed normal experiment three times with four speeds. Next, we performed spasticity experiment with same way. We analyzed kurtosis and skewness to evaluate the obtained data. We can measure the spasticity by measuring the dynamic pattern of the reaction forces and angles, and, confirm changes in kurtosis and skewness in four flexion speeds. However, we found many improvements such as arm length and flexion speed. In the future, we will measure real patients.

This study proposes a conceptual model of risk assessment for insider threats detection in Cyber-Physical system (CPs). The objectives of this research are two folds: a) finding the gap of study and b) produce a conceptual model of risk assessment for insider threats. This study has been conducted since an increasing number of cyber-attacks cases reported in CPs. In fact, the attack occurs unintentionally or intentionally from inside and outside of the organization due to the growth of new devices, sensors and mobile phones that connected to the network. However, to charge that the attack is coming from inside is more difficult since lack of evidence and involved cyber laws. Therefore, to detect insider threats demand new approach for better decision making. Current methods used for detecting insider threats are OCTAVE, FRAP, CRAMM, NIST, Monte Carlo and Markov Chain. Based on our findings, Monte Carlo and Markov Chain is a simulation-based method and applicable for organizations in terms of effective cost and system maintenance. The impact of the new model brings a better solution for assessing insider threats in organizations.

This paper presents the power management system (PMS) that relies on optimal power planning and maximum energy efficiency in dynamic positioning (DP) drilling vessel. Nowadays, it is becoming an improving demand for higher precision and decreases ship motion induced by environmental disturbance such as wind, waves, and sea current, which leads to the use of power generation more efficient. According to this, an efficient strategy solution and schedule have increased significantly for power management of diesel generator (DG) units on marine vessels as an independent microgrid to the utility grid. Thus, the power management system (PMS) of vessels is proposed to monitor and prevent the blackout by using the model predictive controller (MPC) based on optimal control method in order to estimate the future power demand in the hostile environment. Due to nonlinear characteristics of diesel generators, such as power ramp rate limits and non-smooth cost functions, a particle swarm optimization (PSO) is applied to solve the economic dispatch (ED) problem for a dynamic system. The simulation results demonstrate that the proposed method can improve ED operation problems more efficiently while meeting DGs constraints.

The demand for indoor localization that does not rely on the presence of any external infrastructure had been increasing. In general, an indoor localization system was required to be precise, highly accurate and reliable. In this paper, we presented and analyzed an indoor localization wearable device that was capable of positioning people while riding in an elevator. The inertial measurement unit (IMU) was utilized with an embedded system on the device. Current approaches involving IMU mounted on a pedestrian's body generally estimated the displacement on the ground only (in two dimensions). Thinking of a wearable device to estimate the vertical distance for elevator riding and with the fact that there are different levels of height for different buildings, a new algorithm was proposed to estimate distance in vertical direction when people riding in an elevator. The proposed algorithm was based on the double integrating process from global acceleration with gravity removal in which the velocity and distance are updated in periods that the vertical acceleration oscillates around Zero level. Experiments with a wearable device which was designed based on the IMU model MPU9150, Arduino board and wireless Xbee took place for riding in an elevator. Experimental results contained device's attitude, vertical distance and time stamp. They were recorded online wirelessly via Xbee devices into an *txt file. Experiments in this work include riding up and down in an elevator. They were repeated to collect data for evaluation by root mean square error (RMSE) computation based on the ground-truth. The experimental results demonstrated RMSE of 0.77%, 0.88%, 1.66% riding in an elevator through one floor only, riding in an elevator through multiple floors while stopping at each floor, riding in an elevator through 40 floors, respectively.
